Thread: Loose leads wiring question.

  1. #1

    Default Loose leads wiring question.

    Ford Holley HP kit 550-606N. I wanted to check and ask what would be the best way to connect the loose leads in my kit please. I have an MSD 6 CD box in my glove box and coil in engine bay already hooked up before my Holley HP install. What would I do with the points output (white), ignition ground (black), and coil (yellow)?

    I need to find a switched 12V battery lead for the red wire and the other single loose lead red/white wire.

    Can I leave the 12V fuel pump wire (green) unused and have the Holley HP still function properly? I have a 12V Aeromotive fuel pump already hooked up and my skill is limited with this install. Thank you.

    I need to find a switched 12V battery lead for the red wire and the other single loose lead red/white wire.
    Also, ensure the Switched +12V red/white wire (pink wire - Sniper EFI) is powered in the "Run" and "Crank" key positions.
    The ignition switch must have a wire that's powered in "run" and "crank" key positions leading to the ignition system.

    Can I leave the 12V fuel pump wire (green) unused and have the Holley HP still function properly?
    Yes, you don't have to use the green fuel pump wire. However, it can also be used to trigger an existing fuel pump relay.

    Thank you Danny! Would that mean I run the white wire to my MSD box and not use the ignition ground (black) and coil wire (yellow)?
    I still don’t have the 558-305 connector purchased for the Holley HP or the 565-201 Dual Sync distributor I'm still deciding on.

    You'll use the loose black wire, but not the loose yellow wire.
